The present handbook is reported to the SPC 03 card release 270888 and later. The validity of thebring informations is subordinate to the number of the card release. The user must always verify thecorrect correspondence among the two denotations. On the card the release number is present in morepoints both on board printed diagram (serigraph) and printed circuit (for example on the bottom edgeon the component side, or inside JAF component area on the solder side).



GENERAL FEATURESGENERAL FEATURES

The SPC 03 module is a complete switching power supply with standard single Europa size suitedfor ABACO ® and GPC® cards. This feature allows a direct use inside 3HE Rack together with thecards it supplies power to and it simplifies the mounting and replacement of the same cards. Moreoverit is designed to match to other motherboards as YPB 01, SPB 04, SPB 08, etc obtaining asignificant time reduction for install and link phases.The SPC 03 generates all the standard voltages required by microprocessor based systems, startingfrom a single AC or DC low input voltage, so it respects the security norms.Some LEDs on the front side inform about the presence of the output voltages and they add thepossibility to visually diagnose any possible failure .A very important feature of SPC 03 is an auxiliary input coming from an external battery; in this caseit works like an UPS (Uninterruptible Power Supply), assuring power to the loads, with nodiscontinuity, even without external mains voltage.The SPC 03 is available in 7 different models that have different generated voltages and differentmaximum load currents, as described in the following table:

Model Voltage Current Note SPC 03 5 Vdc 4 A With Power Failure SPC 03.12 12 Vdc 4 A - SPC 03.15 15 Vdc 4 A - SPC 03.24 24 Vdc 4 A - SPC 03.VT 5÷40 Vdc 4 A Voltage regulated SPC 03.VB 5÷40 Vdc 0.2÷4 A Voltage and current regulated SPC 03.3T +5; +12; -12 Vdc 3.5; 0.15; 0.15 A With Power Failure

The total supplied power is about 50 W in ambient temperature up to 60 °C, but with a proper forcedventilation a power of 120 W can be reached without problems.

- Single Europa size measuring 100x160x25 mm- Electrical connection by the strong connector DIN 41612 type F- Matching mechanically and electrcally to YPB 01, SPB 04, SPB 08, etc.- Up to 3 coloured LEDs which indicate the presence of the generated voltages, placedon the front side

- Noises reduction filters on the inputs and outputs- Power failure digital signal that can be used as reset for the other cards- Reference and regolation signals available on connector- Protection on over temperature, over output voltage and short circuit- Input for auxiliary voltage from a 12, 24 Vdc battery, for UPS function- Medium performance higher than 80%- Required voltage: 8÷28 Vac or 12÷40 Vdc (according to selected model)- Generated voltages: variable according with selected model (see previous table)

RECTIFIER SECTION

The alternate (AC) input voltage to SPC 03 is filtered through a MOV, which eliminates transients,then it is rectified by the specific rectifing section that generates a DC voltage for the switching powersupply. Rectifing section is made of a simple bridge rectifier with capacitors that assure a direct (DC)voltage erogation in all the operating conditions of the power supply. Components are selected toreduce the value of ripple of the switching regulator input, whatever input voltages or output loadsare connected. Rectifier section is always present but, as indicated in the block diagram, it is usedonly in part if a DC voltage is provided as input. In such condition the bridge rectifier is not used andthe input voltage is just filtered by the capacitors.The presence of two different inputs for AC voltage and DC voltage allows the possibility to use thepower supply as an UPS (connected, for example, to a battery) and provides the possibility to haveoutput voltage referred to the same potential of input voltage.

SWITCHING REGULATOR

SPC 03 power supplies are based on an efficent switching regulator that performs the task to keepthe output voltage under control and to limit the output current. The main component of this sectionis an integrated voltage regulator that belongs to family GS-Rxxxxx manufactured by SGS. Thesemodules have been designed specifically to build industrial power supplies of middle-high powerwith best price/peformance rate and a good reliability, due also to its almost total absence of externalcomponents. Including all the 7 models of SPC 03, the overall features of switching regulationsection are:

- soft start of power supply after a power on- high efficency, up to 80%- protection against overcurrent or output short circuit- protection against overheat- protection against output overvoltage- 100 KHz switching frequency- step down regulation- automatic compensation of voltage drop due to connection cables- generation of /RESET signal for power failure functionality- signal (INHIBIT) that disable and enable the regulator- huge heatsink- MTBF greater than 200000 hours- low noise and reduced output voltage ripple

Also in this section components have been selected to reach maximum efficence and warrant anywaythe maximum output current 4 A for the selected output voltage.Some components of the regulation section may vary according to the model selected, so the outputvoltage selection cannot be made by the customer but must be specified in the order.The following list reports the type of regulator used for each model of SPC 03 and its differencesrespect to the above listed features:



FIGURE 2: SWITCHING REGULATORS GS-RXXXXX

OUTPUT SECTION AND FILTERS

Output section of SPC 03 simply filters the stabilized voltages generated by the switching regulatorthrough specifc capacitors (for high and low frequencies) and visualizes the power supply status byspecific LEDs. Some components of this section may vary according to the model selected and, asusual, all components have been selected to assure stability of output voltage under any operatingcondition. As described in the block diagram +5 Vdc output voltage is provided with further filterthat reduces high frequency noise.Another feature of output section is to include some jumpers (A1÷A5 and B1÷B5) that allow the cardconfiguration for the requested model; these jumpers are connected by grifo ® technicians duringmounting phase and they can't be changed by the user.

INSTALLATIONINSTALLATION

In this chapter there are the information for a right installation and correct use of the card. The usercan find the locations and functions of each connectors, LEDs and some explanatory diagrams thatshow the best operating conditions and suggested use modalities.

VISUAL FEEDBACK

SPC 03 modules are provided with LEDs to signal status conditions, as described in the followingtable:

FIGURE 3: VISUAL FEEDBACK TABLE

The main purpose of these LEDs is to give a visual indication of the board status, making easier theoperations of system working verify. In the models with adjustable output voltage (SPC 03.VT andSPC 03.VB), brightness of LED L1 is directly proportional to output voltage, so it will be weaklybright or even OFF for the minimum +5 Vdc voltage.To easily locate these LEDs on the board, please refer to figure 4.

CONNECTIONS

The SPC 03 power supply has one connector that can be linkeded to other devices or directly to thefield, according to system requirements. In this paragraph there are connectors pin out, a short signalsdescription (including the signals direction), connections examples and detailed regulation description,for each one of the 7 models. The following connectors views use standard numeration of pins: suchnumeration is easily recognizable by connector internal print or board printed serigraph.DIN 41612 type F connector, that can be connected directly to grifo ® cards like YPB 01, SPB 04,SPB 08, simplifies cabling phase and allows a faster replacement of the whole power supply in caseof possible damage or manteinance. Moreover, the wide contact surface assures a good transport ofpower provided and fetched. Value of input voltages and powers varies in a wide range as describedin paragraphs “ELECTRIC FEATURES” and “POWER PROVIDED”.

OUTPUT VOLTAGE ADJUST FOR SPC 03.VT

The regulated output voltage +Vdc OUT can be adjusted through a resistor RPRGV

connected on pin18d (SENSE+) and the specific pin 14d (PRG V) of CN1. The value of such resistor is obtained bythe following formula: R

PRGV =2.67*((+Vdc OUT/5.1)-1) KΩ

so it may vary in the range 0÷18 KΩ corresponding to a variable output voltage in the range 5÷40Vdc. To obtain an adjustable output voltage power supply it is sufficient to connect a 18 KΩpotentiometer or trimmer, as rheostat, between pins 14d and 18d of CN1, as descirbed on figure 14.

OUTPUT VOLTAGE AND CURRENT ADJUST FOR SPC 03.VB

The regulated output voltage +Vdc OUT can be adjusted through a resistor RPRGV

connected on pin18d (SENSE+) and the specific pin 14d (PRG V) of CN1. The value of such resistor is obtained bythe following formula: R

PRGV =2.67*((+Vdc OUT/5.1)-1) KΩ

so it may vary in range 0÷18 KΩ corresponding to a variable output voltage in the range 5÷40 Vdc.The maximum current before overload protection intervents can be adjusted through another resistorR

PRGI connected on pin 18z (SENSE-) and the specific pin 18b (PRG I) of CN1. The value of such

resistor is given by: RPRGI

=5.08*IPROT+1.18 KΩso must be greater than 2,2 KΩ corresponding to the minimum 0.2 A output current.To obtain an adjustable output voltage and current power supply it is enough to connect twopotentiometers or trimmers, as rheostats: a 18 KΩ between pins between pins 14d and 18d of CN1,a 2,2 KΩ between pins 18z and 18b of CN1, as descirbed on figure 16.

OUTPUT VOLTAGE LOAD SENSING

Every power supply model, except SPC 03. 3T, is provided with a professional sensing circuiterythat allows to work correctly also in critical connections situations. This feature allows the powersupply to compensate autonomously the possible voltage drop across the connection cables that carrythe regulated tension to the load.The sensing signals SENSE+ and SENSE- must be connected respectively to positive signal(+xx Vdc OUT) and negative signal (GND xx) of the regulated output voltage, directly on thesupplied load at the farest distance from SPC 03. This connection must be always performed: if theconnection is uncomfortable or useless it is simply possible to short circuit the described signalsdirectly on CN1 connector, as below described:

18d to 16d and 18z to 20z on SPC 0326z to 24z and 26d to 28z on SPC 03.1218d to 12d and 18z to 20z on SPC 03.15, SPC 03.24, SPC 03.VT, SPC 03.VB

by granting that external conditions allow this special connections (sufficient cable size, notinductive load, short distance connection, etc.).Please remark that grifo ® mother boards already make the connection of sensing signals directly onthe printed circuit board.Previous figures with connection example for each models, show the suggested connection forsensing signals.

INPUT VOLTAGES AND UPS

Connector CN1 features two pins for AC input voltage and two separated pins for DC input voltage;these should be used only in the possible combinations described here:

1) Single AC voltage on pins Vac1 IN and Vac2 IN of CN1;2) AC voltage on pins Vac1 IN and Vac2 IN and back up DC voltage on pins +Vdc IN and -Vdc IN of CN1;3) DC voltage on pins Vac1 IN and Vac2 IN of CN1 and back up DC voltage on pins +Vdc IN and -Vdc IN of CN1;

Pleasse remark that -Vdc IN signal is physically connected to GND xxx signal to warrant the sameground potential between output voltage and DC input voltage; differently, in case 3 ground of DCinput voltage is not physically connected to ground of regulated output voltage. In fact the twogrounds differ of about 1.5 V, that is the typical difference of potential due to the bridge rectifier.In cases 2 and 3 SPC 03 acts as an UPS (Uninterruptible Power Supply): when the voltage on pinsVac1 IN and Vac2 IN is no more available the regulated output voltages are still present through backup input voltage, which is usually provided by a suitable battery.



FIGURE 19: SPC 03 PHOTO



PROTECTIONS

Modules SPC 03 feature the typical protections that allow to save them against improper uses andcontemporarily assure that the power supply remains in the range of nominal working values. Indetail the power supply is provided with 5 different protections:

Overheat Switching regulation section keeps under control its own workingtemperature so when this latter exceeds 150 °C it disables the outputvoltage to allow the temperature to decrease.Output is automatically restored when the temperature value get lowerthan 130 °C, so the 20 °C hysteresis prevents instable output conditions.

Overlaod Switching reguation section keeps under control output current onCN1 so when current exceeds 5 A it disables the output voltage. Afterthis, current is automatically restored softly. Soft start delay assures alimitation on output current in case the overload condition is stillpresent.

Short circuit Managed as overlaod condition.

Input overvoltage Input section is provided with a MOV filter that suppresses somenoises and keeps AC input voltage (supplied to rectifire section) under39 Vac to protect switching regulator. In case the input overvoltagepersists, MOV filter can damage and must be replaced.

Output overvoltage Switching reguation section keeps under control output voltage; whenthis latter exceed 20% of nominal value it disables the output voltage.To restore the output, switching regulator must be turned off byremoving any input voltage.

After protection intervent, output voltage restore is always performed gradually (soft start), withgradual power increase.

NOTE It is always a good practise to insert an opportunely dimensioned protection fuse on inputvoltage, both AC and DC, to keep safe the power source.

/RESET AND POWER FAILURE

Switching section of models SPC 03 and SPC 03.3T generates a /RESET signal that informseventual users of regulated output voltage validity. In detail /RESET is a digital TTL signal that canhave two possible stautus.

/RESET = +5 Vdc -> +5 Vdc regulated output voltage is valid/RESET = GND -> +5 Vdc regulated output voltage not valid because input voltage is too

low or output voltage is out of range



The sections warrants at least 100 msec of duration for the signal to provide enough intervent timeto the external connected circuits.Previous description shows that /RESET signal acts also as power failure and can be matched tomicroprocessor based boards with the same signal, with no problem. As usual, grifo ® mother boardsalready connect /RESET signal to the corresponding signal on CPU board (/R.T.), directly on theprinted circuit.

FIGURE 20: COMPONENTS MAP



POWER PROVIDED

Power supply SPC 03 can provide a maximum power that changes according to the model, asdescribed in the following table:

FIGURE 21: POWER TABLE FOR EACH MODEL

Values of input power reported are referred to average efficency of power supply (80%) andincreased of 10%. For safety it is always opportune to choose a greater power and an input voltageclose to the maximum value reported. To obtain maximum output power it is essential to provide aninput voltage with the features specified in figure 21 considering that such values are referred to anenvironmental temperature of 20 °C. Changes of this temperature may influence remarkably bothmaximum output power and output voltage: the user must employ all techinques to keep temperaturein admitted range. Should thermal dissipation be insufficent, an additional heatsink can be mounteddirectly on IC1 swithcing regulator, fastening it the four holes in the top corner of the module.SPC 03 features components and circuites designed to reduce noise sensibility and increaseefficence; also, the lay out has been carefully tracked to carry thegenerated power in the best waypossible, avoiding mass rings, instability, emissions, etc.

MODEL IDENTIFICATION

The seven different models of SPC 03 can be easily recognized through two proper areas placed onprinted circuit serigraphy: one on component side near the right side of the switching regulator andone on solder side in the specific table under IC1. After the preparation and the testing phase in boththese areas are manually noted the realized model, so the user can immediately identify it, withouterrors.Figure 4 of this manual shows the location of the model identification areas.
